My little side is 4-5 years old, already potty trained but sometimes wets the bed, is prone to accidents when she's excited or really focused on something, and has trouble holding it for too long if she can't get to the potty quickly. I love the idea of a mommy or daddy reminding me to go potty at bedtime, before going on car rides, or asking me if I need to go when he/she sees me doing the potty dance but not wanting to stop what I'm doing.
